190b9470a4 docs(telemetry): fix xrpl.network.type value (standalone → unknown)
The network-type label is derived from [network_id] in TelemetryConfig.cpp;
unmapped/unset IDs fall through to "unknown", not "standalone". Align the
design-doc resource-attribute table with the code and cfg example.

c3ccde3e39 docs(telemetry): document the span-attribute naming rules
State the rules so they stay consistent across code, collector, Tempo,
dashboards, and docs:

- Per-span-unique field -> bare name (the span name carries the domain).
- Same concept on more than one span -> ONE shared key, reused verbatim and
  distinguished by span name, never tagged with the emitting workflow
  (e.g. ledger_hash, full_validation, proposal_trusted/validation_trusted).
  Defined once in the base SpanNames.h and re-exported by each domain header.
- Collision qualifier <domain>_<field> only to separate DIFFERENT concepts that
  share a word, or the OTel-reserved status key (rpc_status, consensus_state).
- Dotted xrpl.<...> is reserved for resource attributes (xrpl.network.*).

Updates CONTRIBUTING.md (permanent home) and OpenTelemetryPlan §2.3.3.

c0272f1314 docs: Add span attribute naming convention (OTel phase 1a)
Establish the single, authoritative naming convention for OpenTelemetry
span attribute keys so the code, collector, Tempo, dashboards, and docs
stay in sync.

- CONTRIBUTING.md: new "Telemetry span attribute naming" section under
  the Style guide as the permanent, canonical home for the rules.
- OpenTelemetryPlan/02-design-decisions.md: new section 2.3.3 stating the
  decided convention as design, and section 2.4 attribute schema realigned
  to the underscore form (exact key spelling defers to the *SpanNames.h
  constants).
- Sweep the remaining plan docs: convert dotted xrpl.<domain>.<field> span
  attribute keys to the underscore form; leave span names and the
  OTel-standard service.*/http.* and xrpl.network.* resource keys dotted.

fe13359024 docs(telemetry): enable peer tracing by default in plan docs
Flip trace_peer default false->true across the Phase-1a plan docs and
correct the rationale: peer spans record only peer_id (numeric local
connection id) plus trust/ledger metadata, never IP addresses or public
keys, so the 'includes addresses' caveat was inaccurate. The high-volume
note is retained.

f3a095ab65 docs(telemetry): align Phase 1a plan docs with Phase 1b implementation
Phase-1a plan documents advertised OTLP/gRPC on port 4317 as the default
exporter, four unparsed [telemetry] config keys, and "Phase 4a Complete"
status with exit-criteria checkboxes marked done. Every downstream branch
through Phase 5 ships only OTLP/HTTP on port 4318 via OtlpHttpExporterFactory,
never parses the advertised keys, and the Phase 4 work is not yet delivered.

Fixes:
- 02-design-decisions.md: flip §2.1.1 SDK dependency recommendations to
  OTLP/HTTP (shipped) with OTLP/gRPC marked Future. Update §2.2 architecture
  diagram and text from OTLP/gRPC:4317 to OTLP/HTTP:4318. Rewrite §2.2.1 as
  "OTLP/HTTP (Shipped)" and §2.2.2 as "OTLP/gRPC (Future Work — Planned
  Upgrade)" with a concrete checklist (Conan dep, config parsing, factory
  branch, runbook/dashboard updates) for landing the gRPC transport later.
- 05-configuration-reference.md: drop the fabricated exporter/otlp_grpc key
  and the :4317 default from the sample config block and the options-summary
  table. Move trace_pathfind, trace_txq, trace_validator, trace_amendment
  into a new "Planned (not yet implemented)" table citing the phase that will
  add each one. Keep the example config minimal so copy-paste does not produce
  a silently-ignored stanza.
- 06-implementation-phases.md: reset Phase 4 Exit Criteria checkboxes from
  [x] to [ ] (Phase 4 is not shipped at Phase-1a time). Rename "Phase 4a
  Complete" to "Phase 4a Plan" and describe the work as future. Replace the
  broken forward link to Phase4_taskList.md (introduced in the Phase 2 PR)
  with a sentence pointing readers to where that spec will land. Renumber
  the final section 6.12 to 6.11 so it sits directly after 6.10; section 6.11
  ("Effort Summary") was intentionally removed in earlier edits.

1fd971b78b fix(docs): apply rename scripts to OpenTelemetry plan docs
Run .github/scripts/rename/docs.sh to replace rippled → xrpld
references in all plan documentation files, fixing the check-rename
CI failure.

913a4b794c docs: correct OTel overhead estimates against SDK benchmarks
Verified CPU, memory, and network overhead calculations against
official OTel C++ SDK benchmarks (969 CI runs) and source code
analysis. Key corrections:

- Span creation: 200-500ns → 500-1000ns (SDK BM_SpanCreation median
  ~1000ns; original estimate matched API no-op, not SDK path)
- Per-TX overhead: 2.4μs → 4.0μs (2.0% vs 1.2%; still within 1-3%)
- Active span memory: ~200 bytes → ~500-800 bytes (Span wrapper +
  SpanData + std::map attribute storage)
- Static memory: ~456KB → ~8.3MB (BatchSpanProcessor worker thread
  stack ~8MB was omitted)
- Total memory ceiling: ~2.3MB → ~10MB
- Memory success metric target: <5MB → <10MB
- AddEvent: 50-80ns → 100-200ns

Added Section 3.5.4 with links to all benchmark sources.
Updated presentation.md with matching corrections.
High-level conclusions unchanged (1-3% CPU, negligible consensus).

Also includes: review fixes, cross-document consistency improvements,
additional component tracing docs (PathFinding, TxQ, Validator, etc.),
context size corrections (32 → 25 bytes).
